AC variable-frequency drive - 2.4 - 5 A
The Bison variable frequency drive is lightweight and housed in a plastic NEMA 4X enclosure. It has a minimum speed adjustment potentiometer, DC injection braking, output voltage doubling, isolated front end and manual or automatic restart upon the restoration of power. The NEMA 4X enclosure is easily mounted, compact and made of black plastic. The isolated inputs can accommodate grounded or floating signals 0-10 VDC, 0-5 VDC or 4-20 VDC. The calibration pots are user adjustable in terms of maximum and minimum speed, deceleration, acceleration, current limit, boost, slip compensation, sero set, brake time and brake current. The diagnostic LED displays power, torque limit and fault. It has stopping modes for DC injection braking or coast. The switching frequency is adjustable 4 to 16 kHz. The motor has less electrical noise and quiet operation. The quick disconnect terminal block allows 200% maximum torque to handle intermittent peak loads.
